APPARATUS FOR DISTILLING WOOD.

SPECIFICATION forming part of Letters Patent No. 417,752, dated December24, 1889.

Application filed June 20, 1889- Serial No. 314,948. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL H. SPANGLE-R, a citizen of the United States,residing at Palestine, in the county of Anderson and State 5 of Texas,have invented certain new and useful Improvements in Furnaces andApparatus for-Distilling ood; and I do declare the fo llowing to be afull, clear, and exact description of the invention, such as will enable19 others skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specificar5 tion.

My invention has relation to improvements v 'in furnaces and apparatusfor distilling wood of that class wherein the liquids of the wood areextracted by subjection in aclosed heated 2o chamber or retort andcarried by vaporization through the process of distillation tocondensation.

The improvements involved in my invention are fully illustrated in theaccompany- 2 5 ing drawings, and hereinafter I have specificallydescribed the same, so as to distinguish my invention from otherinventions.

In the drawings, Figure 1 is a front view, in elevation, of the furnace.Fig.2 is a rear View, in elevation, of the furnace, a portion beingshown removed to illustrate the retortpipe. In this figure are alsoshown the receiver, the dome with the deflector, and the exhaust pipe.Fig. 3 is a longitudinal central section 3 of the furnace and retort andvertical section of theretort-pipe, the receiver, and dome, a car beingshown in position in the retort. Fig. 4 is a view of the water-box andcondensing-pipes with the discharge-pipe. 40 A designates the brick-workof the furnace having end walls and side walls to properly inclose,surround, and support the retort.

In the front of the furnace are openings 1 and 2, the former leadinginto the fire-chamber of the furnace, and are closed by doors 3,properly mounted and closing tight, and the latter openings 2 leadinginto the ash-pit and provided with doors 4 to close them. Thefire-chamber is provided with grate-bars 5, arranged over the ash-pit G,with one end resting in the front wall of the furnace and the other orrear end resting on the bridge 7 the lower part of which forms the backwall of the ash-pit, and the bridge being built to a proper height inthe furnace to throw the flames upward and into the combustion-chamber 8at the rear. Transversely arranged across the furnace are a sufficientnumber of supporting-bars 9, having their ends fixed in the masonry ofthe furnace, and these support the retort.

B designates the retort. This consists of a chilled-'iron-plate bottom10, resting on the supporting-bars 9, and a fire-clay body 11, havingvertical sides and arched top or roof, substantially as shown. This claybody 11 may be molded and built of plastic material or composed offire-clay bricks laid up to suit the construction, with iron end facings1213 at front and rear bracing the masonry of the retort and furnace andhaving the ends closed by doors 14 15, fitting gas-tight over theopenings of the retort. The retort is arrangedin the masonry with adraft-space about its sides and top, to which the draft of the fur- 7 5nace communicates through fiues 16, located at the rear of the furnace.At the front is the stack 17. The stack orfiues are provided withsuitable dampers to control the draft of the furnace. At the front ofthe furnace is arranged a pyrometer 18, from which the condition of theheat in the retort may be ascertained. In the center of the retort isfixed the vertically-arranged escape-pipe 19, through which the escapinggases are carried into a cylindrical receiver 20, located on the top ofthe escapepipe, The escape-pipe extends up in the reservoir, as shown,with its open end arranged directly under an inverted cone-shapeddeflector 21, which deflects and 0 distributes the rising fumes or gasesabout in the reservoir,causing precipitation of any solid or tarrymatter which may be carried forward by the gases. At each end of thereservoir is a hand-hole 22, through which access to the reservoir maybe had for the purpose of removing the deposits. These hand-holes arecovered by caps or doors 23.

In the bottom of the reservoir is a spigot 24, through which the liquiddeposits may be I00 discharged when desired. Over the deflector 011 thereceiver is secured a dome 25, which has an exhaust-pipe 26, connectedto its top. This exhaust-pipe is curved above its connection to thedome, substantially as shown, and has in it an exhaust-fan 27, operatedby any suitable mechanism. From the exhaustfan leads the conveying-pipe28, having a connection with the exterior vertical pipe 29 of thecondensing-pipes in the water-box.

O designates the water-box. This is made of suitable dimensions toreceive the condensing-pipes, and is provided at the bottom with afeed-pipe 30 and at the top with a discharge-pipe 31, whereby thecontents of the water-box may be constantly supplied and kept freshthrough the discharge-pipe. the water-box are the condensing-pipes32,being composed of vertically-arranged pipes connected at their topand bottom, the con nections 33 at the bottom being disposed on theoutside of the box and provided with spigots or cocks 34, by which theprecipitated and condensed deposits remaining in the pipes may bedischarged as desired. The upper end of the last arm of thecondensing-pipes projects from the water-box, as at Z2, and hasconnected thereto a small worm-pipe 35, through which the volatile gasesescape or are conducted to such reservoir (not shown) as may be suppliedfor their retention or distribution.

At the rear of the retort is a tramway36, on which the cars 37containing the materials to be treated, are conveyed. The trucks or carsare provided with metal boxes to retain the materials to be treated, andare run into and out of the retort through the openings covered by thedoors. 1

Having thus described my invention, so to distinguish it from other andprior inven tions, I proceed to particularly point out the parts andcombinations I claim as myinvention, as follows:

1. In an apparatus for distilling woods, the combination, with theheating-furnace, of a fire-clay retort provided with a metal bottomarranged directly over the fire and combustion chambers of the furnace,a vertically-arranged escape-pipe in the roof of the retort, a receiveron the upper end of the escape-pipe provided with a deflector arrangedover the end of the escape-pipe, a dome 0n the receiver arranged overthe deflector, and an exhaust-pipe attached to the dome, substantiallyas described.

2. In an apparatus for distilling woods, the combination, with a furnacecontaining a closed retort, of an escape-pipe leading from the retort, areceiver mounted on the escapepipe with the end of theescape-pipe'projecting into the receiver, a deflector in the receiverarranged over and above the open end of the escape-pipe, a dome over thedeflector, an exhaust-pipe provided with an exhaustfan, a conveying-pipeleading from the exhaust-fan, a water-box, a series of condensingpipesarranged in the water-box with the upper end of the last pipe thereofprojected from the box, and a small coil-pipe attached to the end of thecondensing-pipe, substantially as described, and for the purposespecified.

3. In an apparatus for distilling woods, the combination, with theconveying-pipe leading from the retort, of a tight water-box providedwith an inlet-pipe at its bottom and an outletpipe at its top, a seriesof condensing-pipes arranged in the Water-box with their lower endsconnected by elbows projected below the bottom of the water-box andprovided with drain-cocks, and a coil-pipe arranged outside of thewater-box, having its upper end connected to the upper end of thecondensingpipe, substantially as described, and for the purposespecified.

In testimony whereof I affix my signature in presence of two witnesses.
